Automatisierte universelle CCD-Astrometrie von Kleinplaneten
(Univ. Dresden, 2005)
Für Zwecke der differentiellen astrometrischen Positionsbestimmung von Kleinplaneten werden heutzutage verbreitet CCD-Beobachtungen eingesetzt. Insbesondere im Rahmen von Follow-up-Beobachtungsprogrammen sind eine Vielzahl ...
The sediment record of Lake Ohrid (Albania/Macedonia)
(Univ. Köln, 2009)
This thesis had two primary objectives: One objective was to explore and develop applications of Fourier transform infrared spectroscopy (FTIRS) for the quantification of biogeochemical properties in lake sediment; the ...
Turbulenz im interstellaren Medium
(Univ. Bochum, 2005)
In der vorliegenden Arbeit wird die Heizung des interstellaren Mediums durch die Dämpfung von Plasmawellenturbulenz untersucht. Es wird gezeigt, daß die Heizung ausreicht, das thermische Gleichgewicht im interstellaren ...
Internal characteristics of magnetic clouds and interplanetary coronal mass ejections
(Univ. Braunschweig, 2005)
Coronal Mass Ejections (CMEs) are extremely dynamical and huge events in which the solar plasma, initially contained in closed coronal magnetic field lines, is ejected into interplanetary space. When a CME is detected ...
Cosmological solutions of the Einstein-Vlasov-scalar field system
(Univ. Berlin, 2005)
The aim of this thesis is to obtain as much information as possible, about global solutions of the Cauchy problem for the Einstein-Vlasov-scalar field system with spherical, plane and hyberbolic symmetries written in areal ...
Constraining the UV background with the proximity effect
(Univ. Potsdam, 2009)
After the epoch of reionisation the intergalactic medium (IGM) is kept at a high photoionisation level by the cosmic UV background radiation field. Primarily composed of the integrated contribution of quasars and young ...
Erste Beobachtungen mit dem abstimmbaren Infrarot-Heterodynsystem THIS
(Univ. Köln, 2005)
Gegenstand der vorliegenden Arbeit ist die technische Weiterentwicklung des durchstimmbaren Infrarot-Heterodynsystems THIS (Tuneable Heterodyne Infrared Spectrometer) sowie die Planung, Vorbereitung und Durchführung diverser ...
Energetic particles in the Jovian magnetosphere and their relation to auroral emissions
(Univ. Zugl.: Braunschweig, 2005)
This thesis discusses the relation between the energetic particle characteristics measured by Galileo in the inner to middle Jovian magnetosphere, and the auroral emissions observed by the Hubble Space Telescope. The thesis ...
Quaternary tectonics and seismic stratigraphy of the western Black Sea shelf
(Univ. Hamburg, 2009)
Interpretation of high and very high resolution reflection seismic data from the western Black Sea shelf yielded a seismic stratigraphic model of the Late Quaternary deposits on the southwestern Black Sea shelf. This model ...
Late Quaternary environmental history of Taylor Valley, southern Victoria Land, Antarctica, reconstructed by a multidisciplinary study of lake sediments
(Univ. Köln, 2009)
In the unglaciated areas of Antarctica, lake sediments act as archives of the regional environmental and climatic history. In most cases, the records are restricted to the Holocene. Amongst the few exceptions are lakes in ...
